Back

Multi-layered tissue. Cells along Basement membrane are active and dividing. Basal cells are cubodial/comlumnar as they mature and are pushed to the surface they become squamous cells. What Epi tissue?

Cell or group of cells that have the ability to maufacture and discharge a secretion and are derived from epi.

Gland

Name Ways Glands are Classified?

Prescence or abscence of ducts.
# of cells that compose them.
Type of secretion
Shape of ducts
Complexity of gland

No ducts
secretions distributed throughout body
Produce & Secrete regulartory chem. hormones into the blood stream or lymph system carried to other regions of the body.

Endocrine Glands

Have Ducts.
Most common.
Discharge secretions via their ducts directly into local areas.
Secretions are local and normally do not enter bloodstream.

Exocrine glands

Name 3 Components of Connetive Tissue?

Fibers
Ground Substance
Cells

Name functions of Connective Tissue

Forms structural connections between tissues
Reserve for Energy
Medium for trasport
immune protection
Frame that supports the body
Heat Production

What is the material that is the medium in which cells exchange nutrients & waste w/ the bloodstream.
Shock absorber
protects delicate cells that surround it

Ground Substance

Name the 3 type of connective tissue fibers?

Collagenous
Elastic
Reticular

Fiber that is found in Ligaments and tendons?

Collagenous Fiber

Thick strong strands.
composed of bundled microfibrils
Great tensile strength.
Sometimes called "white Fiber"
In tissues that are constantly being pulled and stretched.

Collagenous Fibers

Composed of Collagen
Not thick
Thin delicate
Branch into complicated networks
Forms a net for support of highly cellular organs
Such as endocrine glands, & lymph nodes

Reticular Fibers

Brached to form complex networks
Composed of bundles of microfibrils
Can be stretched & contract.
Occur in tissues that are exposed to stretching.
Such as: Vocal cords, lungs, skin,
Sometimes called yellow fibers

Elastic Fibers

What are the 2 major types of cells in Connective tissue?

Fixed
Free (transient)

Name the Fixed Cells

Fibroblast
Adipocytes
Reticular

What are adipocyte cells?

They are fat cells. When they cluster into groups they form adipose tissue.

Large irregulary shaped cells.
manufacture & secrete fibers & gound substance to form their paticular matrix. Each connective tissue has their own?

Fibroblast

Flat star shaped cells
Long outreaching arms that touch other cells. Form netlike connections throughout the tissue they compose.

Reticular Cells

What is the function and Location of Reticular cells?

F/ involved in the immune respone.

L/ found in tissues that are part of the immune system.
Lymph nodes, spleen, bone marrow.

What are free cells?

cells that pass in and out of the connective tissue. Generally repair & protect tissues.
